known as a non-refillable bottle or recep-. tacle of any kind, and has for anobject to provide an improved simple and strong I structure which utilizes the principle of air displacement in its. construction-whereby a refilling is'prevented.

Another object of the invention is to provide a simple strong construction in which there are provided a minimum number of independent moving parts which coact for readily permitting the removal of the contents while positively preventing the escape of air when an attempt is made to refillthe' v bottle, whereby the refilling. fluid cannot enter by reason of the resistance of the air pressure. I

A still further object ofthe invention is to provide a non-refillable bottle closure with a threaded section and a positive locking means for holding the same in place.

In the accompanying drawings :Figure 1 is a longitudinal vertical section through the upper part of a bottle and a closureembodying the invention; Fig. 2 is a view of the upper part of the bottle similar to that shown in Fig. l, the same being shown in a partially inverted position; Fig. 3 is a side View of the structure shown in Fig. 1; Fig. 4: is a section through Fig. 1011 line 4.'-4l; Fig. 5 is a section through Fig. 1 on line 55; Fig. 6 is a detail perspective view of one of the buckets or valve members shown in Fig. 1.

Referring to the accompanying drawings by numeral, 1 indicates the neck of a bottle which may be of any desired structure but is provided with threads 2, which threads are cut away for forming a groove 3 into which a split pin 4 is inserted, as shown in Figs. 1 and 3. This pin is passed through an opening 5 and then automatically spreads by its own resilient action to the position shown in dotted lines in Fig. ,3, whereupon it looks the cap 6 in position and also looks Specification of Letters Patent.

itself against being removed through open- Patented mm, 1915.

ing It is evident that opening 5, if. de'-. 7 1

sired, may be filled with any suitable material after pin at. has been inserted. The

cap 5 is threaded in position on the neck 1 and then the locking member at is placed in position, whereupon the capandithe VfillOllS. parts arranged therem are locked against removal by any one. i

It will beobserved that the cap 6 is pro vided with a depending portion 7 surrounding the-neckof the bottle and with an up;

wardly extending portion or housing S in j which the buckets or valve members 9 and,

10 are mounted. The interior of the housing 8 is provided or formed withany desired number of corrugatlons 11 -=wl11cl1 extend partially across the top, as shown in Fig. I, 5

sides of the housingand also space bucket 9 from the top, as shown in Fig. 2. The housing 8 is, provided with a discharge opening be afiected byany instrument unless bucket [so as to space thebuckets 9 and 10 from the H 9 is broken, as these two buckets are separate and the slight .movem'ent which may be glven to bucket 9..by an instrument inserted through opening 12 will not affect the position of bucket 10.

It will benoted that the bucket 9 faces upv Wardlywhile bucket 10 faces downwardly and telescopes over the tubular portion 13 of the trap 14. The trap 14 is provided with an annular or disk section 15, which section is engaged at the periphery of the gaskets 16 and 17. It will be evident that a notch could be made in the inner part of the top of neck 2 for receiving the peripheral edge of the disk 15 and that one washer could be used instead of two without departing from the spirit ofthe invention. It will be noted that the cap 2 is provided with a recessed portion 1817 01 accommodatingthe peripheral portion. of the disk 15 and the gaskets 16 and 17, as shown particularly in Fig. '1. It is understood that'when the cap 6 is screwed into position the same is operated until the washers 16 and 17 are compressed and then the locking portion 1 inserted, whereby the cap cannot unscrew or become loosened. 'In forming the tubular v i portion 13 of the trap 14 the same is made of such a length as to engage the bottom of bucket 10 simultaneously with the lower edge of the bucket engaging disk 15 of trap 14.

In operation, when it is desired to remove any of'the contents of the bottle the same is inverted to substantially the position shown in Fig. 2, whereupon the fluid will flow out the tubular section 13 and from thence around the buckets or cups 9 and 10 and fin ally out the discharge opening 12. As the cups are made of such a size as to almost touch the ribs or corrugations 11, it will be evident that most of the fluid will flow between these corrugations. If any one should attempt to refill the bottle the inflowing fiuid would trap the air in the bottle before any of the fluid could enter. Also, the fiuid would, by its force, raise the buckets. in case the bottle was inverted until the bucket 10 was engaging the tubular portion 13. The weight of the buckets 9 and 10 will naturally keep the bottle closed when the bottle is in an upright position or in an almost upright position, and the trapped air will prevent the infiowing of any fluid when the bottle is inverted or almost inverted. I

What I claim is t 1. In a bottle or receptacle of the cla-1s described, a threaded neck member having a groove extending transversely of the threads, a cap adapted to be threaded on to said neck, said cap being formed with an aperture, and a resilient locking member formed with flaring upward portions, said locking member being adapted to be inserted through said aperture into said groove, where the flaring portion moves away from the aperture, thus locking the cap against rotation and locking the member against removal.

2. In a device of the character described, a bottle formed with a neck having threads at the upper end, said threads being formed with a groove extending transversely there of, a cap adapted to be secured on to said threaded neck, said cap being formed with an opening and a recess, said recess being F adapted to come opposite said groove, and a locking member formed with resilient flaring portions, said locking member being adapted to be inserted through said opening and through said recess and into said groove, said resilient flaring members moving away from said opening, whereby the locking member cannot be removed and acts as a means for locking the cap against rotation.

8. In a device of the character described, a bottle having a neck, a cap fitting over said neck, means for locking said cap to said neck, a trap arranged in said cap having a tubular portion extending away from the bottle, a bucket telescopically fitting over said tubular portion, a second bucket arranged on top of the first mentioned bucket and facing in the opposite direction, said cap being formed with beads interiorly for guiding said buckets, said cap being also provided with a discharge opening arranged in line with and centrally of said buckets, whereby a tool cannot be inserted between the buckets and the cap.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
